I don't quite understand. getaddrinfo() does not do a reverse lookup.
The problem is: I have a Linux and an AIX system. Both has FQDNs in /etc/hosts
and both are configured to use /etc/hosts first for lookups. On Linux,
getaddrinfo() returns an FQDN when asked for the canonical name of the local
host; AIX returns the unqualified hostname. Since the meaning of
"canonical name" is not defined in either RFC2133 or RFC2553 (and the POSIX
draft is neither final nor public), I must say that both Linux and AIX
comply to the mentioned RFCs.

Then how to expand an unqualified name to a FQDN?
